Re: Service Engine Codes Reply #25 – January 22, 2021, 09:04:26 am Quote from: HiLola - December 19, 2020, 02:49:39 pmConcur the 5W-30 oil for 2017 (09/16 chassis build in my case). However, my 2017 E-series owners manual shows spark plugs and rear axle fluid due at 97,500 miles. Then it states that “transmission fluid and filter (5-speed transmission only) every 60,000 miles. Consult dealer for requirements.”How did you hear about these changes? Is this coming from Ford or your dealer?I got the information from Ford where you are towing another vehicle. In our case a 4,000 lb jeep wrangler. If you are not towing, the mileage goes up. 1 Likes
Re: Service Engine Codes Reply #26 – January 22, 2021, 10:14:00 am You may want to clean the MAF sensor if the output voltage is out of spec range, accumulated dust could shew the air flow measurement.https://www.ford-trucks.com/forums/793764-v-10-6-8l-mass-air-flow-sensor-cleaning.htmlAlso, a vacuum leak is likely as your LD went through some service recently, a careless technician may touch some vacuum tube connectors and cause the leak. To diagnose, have the engine running at idle, spray a small amount of carb cleaner near the vacuum tube connectors, one by one, if the engine suddenly run smooth at that connector, then you find the leak.Good luck

Re: Service Engine Codes Reply #29 – January 24, 2021, 07:17:15 am Here is a picture of the MAF sensor in the E450 1998-2005 V10 air intake system. The air filter housing must be removed to see the sensor hot wire and thermocouple which need to be cleaned. Please use the CRC MAF cleaner fluid to clean it. Use of carb cleaner or brake cleaner will cause damage to the sensor. Never use cotton swab to clean it. Once you clean the sensor, please make sure all air intake hose connections are tight so no vacuum leaks. 2 Likes
Re: Service Engine Codes Reply #30 – January 24, 2021, 12:32:36 pm As shown many times before, Ford's service recommendations for your particular year LD can be found herehttps://owner.ford.com/tools/account/maintenance/maintenance-schedule.htmlOn later model V10s, if the MAF voltage is out of spec, it should set a "Check Engine" light (CEL) and leave a readable code.The hot wire in the MAF is very delicate and can be easily damaged, I would only clean it if a CEL indicates a problem.YMMVLarry 2 Likes

Re: Service Engine Codes Reply #32 – March 08, 2021, 06:33:37 pm Just drove over to Camp SLO from Tehachapi and while waiting to turn left at the 46/101 junction, I noticed the engine was idling roughly and that the service engine had come on again. Hadn’t had any problems since the last incident in January, even after a February trip to the coast.These new codes are different than the previous ones. Today I got a P0300 and a P0308 which is a cylinder(s) misfire. Should I go ahead and clear these codes? Is this something I need to deal with right away?
Re: Service Engine Codes Reply #33 – March 08, 2021, 06:46:11 pm According to this information, 'misfires' with these codes are matters of concern; if my rig were throwing these codes, I would want the problem(s) accurately diagnosed and fixed a.s.a.p.P0300 – Meaning, Causes, Symptoms, & Fixes | FIXD AutomotiveP0308 – Meaning, Causes, Symptoms, & Fixes | FIXD AutomotivePerhaps one of our engine gurus might offer advice? 1 Likes
Re: Service Engine Codes Reply #34 – March 08, 2021, 06:55:38 pm Hi Greg; so the first question is: have you been fiddlin' with plugs coils or wire lately? As new and low mileage as your rig is, you shouldn't have any of these codes. Second question: any sign of rats or mice inhabiting your engine area? Occam's Razor at work. RonB
Re: Service Engine Codes Reply #35 – March 08, 2021, 07:34:56 pm Thanks, Joan.Ron, no fiddling here and no rodent issues as far as I know but I’ll go verify that.
Re: Service Engine Codes Reply #36 – March 08, 2021, 08:34:00 pm Hello Greg,Sorry about your issues but didnt this start after you had a smog check done ?. Jody
Re: Service Engine Codes Reply #37 – March 08, 2021, 08:40:34 pm A P0308 code is definitely a misfire on cylinder 8. A bad ignition coil is the usual cause and is a somewhat common problem on the V10s. We carry an extra coil for such occasions. A less likely possibility is a fail fuel injector.It needs to be checked ASAP before engine damage occurs.When the Check Engine light comes on, it's always best to immediately determine what is going on, engines are expensive.Some codes allow continued driving, others don't.Larry 3 Likes

JodyHi Jody,Yes but the issues I had right after getting a service and smog were different codes (too lean). I found that the service tech had not clamped down the air filter correctly, and after I fixed it, the problem (it was running rough then also) went away and that code didn’t reappear after I cleared it. I have driven over 500 miles since then with no problem until today. Based on what I’m hearing, I may miss the MB meetup. Anyone know any good Ford mechanics on the central coast?

Is this something you think I could drive it a short distance to a repair facility or should I consider towing instead?
Re: Service Engine Codes Reply #40 – March 09, 2021, 12:14:05 pm GregSorry to hear about the trouble. Mullahey Ford in Arroyo Grande - (888) 446-6005 - services Ford Motorhomes. They’ve been very accommodating with me. I wouldn’t be surprised if they might squeeze you in. And, if they can getrdone, your only 30 miles from Morro Bay. Good Luck!Warren
Re: Service Engine Codes Reply #41 – March 09, 2021, 03:01:45 pm Thanks, Warren. I actually spoke to Mullahey Ford’s service department this morning and was told they no longer service motorhomes. I also spoke with Perry Ford and Paso Ford and got no’s from them as well. Turns out Mullahey Dodge in Paso Robles is willing to look at it but I have made arrangements for tomorrow with Jim Burke Ford in Bakersfield to work on it under warranty. I’ve been told that since the dash light is not flashing that I could drive it carefully but if it starts to flash I need to pull over immediately and get a tow, so that’s what I’m gonna try to do.Sorry to miss the get together but will try again next year! Guess I need to call and cancel my site, huh?
Re: Service Engine Codes Reply #42 – March 09, 2021, 03:36:03 pm If the Bakersfield Ford place diagnoses the cause(s) of the codes, please post the outcome. Hope the problem is easily diagnosed and quickly repaired. 1 Likes

If the ignition coil has failed and there is no spark, the unburned gasoline will wash the lubricating oil off the cylinder’s wall, destroying the piston’s rings.This is first hand knowledge, three years ago, coming home from the Morro Bay event, our LD had an ignition failure on one cylinder that didn’t set a code. The result was a ruined engine that earned Ford $8000.’Larry
Re: Service Engine Codes Reply #44 – March 10, 2021, 09:24:17 am Oh boy, how would I do that? And how would that affect the rest of the engine?
Re: Service Engine Codes Reply #45 – March 10, 2021, 09:39:32 am Greg, this is only a suggestion; I have no idea if this shop in San Luis might be able to help, but it might be worth a call to them before you drive over to Bakersfield, particularly if you're not able to disconnect the fuel injector for the #8 cylinder (or any other that is throwing a code). I'm sure this is beyond frustrating, but recalling Larry's experience with 'cylinder wash', I'd try 'local' (out on Tank Farm Road) first. Reeves Auto Repair San Luis Obispo CA, California, Brake Repair, Oil Change,...Good luck.
Re: Service Engine Codes Reply #46 – March 10, 2021, 12:16:35 pm We have decided to let Ford roadside assistance take care of our trip to the Bakersfield Ford dealer. Thank you for all your sage advice and I will post the outcome when I know. 3 Likes

Re: Service Engine Codes Reply #48 – March 11, 2021, 04:12:11 pm Heard back from the dealer. Apparently we had a bad plug in the number 8 cylinder and the engine is now repaired. We're going to pick it up in the morning and head for Morro Bay again. Keeping my fingers crossed! 10 Likes
